AUTOMATIC AUTOGBAPHIC REGISTER,

Application filed July 8,

My invention relates to au-tographic registers which havewithin or applied to them a provide for a tripping or releasing device source of power, such asa spring motor or other automatic driving means. p

' In devices of this character, the great dif fiiculty involved in 'automatic operationis that a very definite amount of paper must be fed at each operation, and. that dupli- I. have found it val uable in the construction of machines of the type described to which does not continue to release the feeding devices, so long as a single depression or throw of the latching elements is ma ntained by the operator, but merely releases them for one complete operation upon one throwing of the latches,- so that all parts must returntto normalprior to a second operation: of the machine. This prevents over-feeding,-with its apparent disadvantages' It isthe object of y invention to provide in anv autographicreg-ister forthe features of advantage above noted,-and generally to provide-a mechanism which will be durable, eflicient and fool-proof.

I. accomplish my objectsv and other ,advantages: to be noted by that certain construction and arrangement of parts .to be hereinafter more specifically pointed out and claimed.

In the drawings,

The figure is a side elevationoi onejform of autographic register embodying my invention. g a

While my invention is shown a applied to registers of the sprocket feed type, it

should not be understood thatthisis the sole type of autographie register feeds to whichit is applicable. I have selected the sprocket feed type because it preserves registry of the strips of paper in :a manner now well known in the art, and because in this type of feed the operating means must be more carefully regulated, stopped and started, in order to prevent'any destruction of the great accuracy-'attainedzzby the' feeding devices, due tofaUltynoperaflOn.

I have shown the invention? as applied to an elementary and simple form ofqsprocket feed register, having no tension roll or tear,-

ing blade. The invention could be V toother types aswell, such as, for example, to my register shown. and: described in. Patent No. 1,259,918, of March 19, 1918,,wheres in instead of an upper tensionroll thereis a springpressed tearing blade, as shown on sheet 1 .of the drawings, or straight bar tearing-blade, as shown on sheet 2. of the drawings.

In the device shown the figure, the

casing of-the machine is shown at 1, and the lid at2, The usual type of sprocket wheels are shown at 3, and strips of paper 4 are illustrated as being fed out of the machine in the usual manner '9 by means ofthe sprockets. i

Mounted on the side wall of the casing,

in this instance on the outside of the casing, is a spring motor, havinga' spring 5, a ratchet and pawl 6 and 7 respectively, and a gear or pinion 8., This springmotor is thus of the same character as the usual clock spring, and in fact it is my desire to usea fairly large clock spring device for operating my register, N o'means for winding the spring is shown-,as this will be of the usual clock sprmgtype. a

Locatedv on the shaft 9 of the sprocket wheel is apinion 10 which meshes with the gear 8 of the spring motor. This pinion has an arm 11 thereon which carries a contact pin 12. The arm 11- isadopted as a convenient means of applying a contact member to the pinion 10, and has; no other function in particular. Itis readily apparent that the spring motorjwill revolve; the pinion 10 and through it the sprocket feeding devices.

.Pivotally mounted at 13 on the side Off the casing isa lever 14, which carries atits one end a stop pin 15, which movesflintoand out of the path of the contact pin-12 con nected to the sprocket operating, pinion 10. The lever is controlled at its other end bya spring 16,. and its movement upward at this end is stopped by means, of a studl'f, in

so that when the lever is free and under the .infiuenceofthe spring, the'stop pin 15 -will beexactly in the path ofthe contact pin 12. The tripping dev-ice'for' the lever comprises a- 'plunger18i, sliding in a housingv 19 22 ofthe lever extends intothe; housing,

and is there engagedby a pawl 23 carried by the side of the casing. This stud-is placed p the plunger and spring-pressed toward the lever end.

The conformation of the end of the lever and the pawl is such that when the plunger is depressed, the pawl operating against the end of the lever will depress it until the pawl rides past the nose 25 on its downward movement whereupon the spring 16 will return the lever 14: to its normal position. When the plunger is released andrises, the pawl will be depressed by the nose 25, riding over this nose and will be returned to its position againstthe offset 24 by the spring 23 and the limit of its upward movement.

The lever 14- will thus operate to release the spring motor for operation at each depression of the plunger, and immediately assume a position which will positively stop the operation of the motor, by moving into the path of the contact pin on the pinion 10. Thus the position of the lever being determined by its spring and thestop above noted, the sprockets will be permitted to revolve exactly one revolution at each depression of the plunger, and the fact that the operator maintains the plunger depressed will have no effect on this operation.

It is also intended as above noted that the basic principle of my invention can be applied to other types of registers, and it is believed that the above two examples will be sufficient to make clear the essential principles involved.

While'a spring motor is shown, it is not desired that I thereby be limited in the application of the points of advantage developed by'my structure to spring motors alone, as some other form of power could be employed, with like results.

Having thus described my invention, what I claim. as new-and desire to secure by Letters Patent, is:

1. In an autographic register, the combination with a spring actuated member and a paper feeding device, of means for operating the paper feeding device connected operatively to the spring actuated member, a release spring held in a normal feed stopping position to permit the spring member to operate said feeding device through one complete movement only, and an operating device comprising a depressible member having means thereon to engage the release and trip it during a portion of its move ment in one direction and free it during the remainder of its motion in said direction, whereby sustained manipulation of said op erating device will not result in continuous movement of the feeding device.

2. In aspring actuated autographic register, the combination with a springactuated pinion adapted to operate the paper feeding element of the register, of a spring latch spring held in a normal feed stopping position adapted when tripped to permit one 1,eee,es2

complete movement only of the spring actuated pinion, and an operating device for said latch comprising a depressible member having means to engage and trip the latch during a portion of its movement in one direction and free the latch in the remainder of its motion in said direction, whereby a retaining of said tripping device out of nor mal position will not result in continued release of the latch.

3. A latch device for a power actuated autographic register, comprising a stop movable with the paper feeding mechanism of the register, and a movable spring stop normally in the path thereof, and a tripping device for the spring stop, adapted to move it out of the path of the first mentioned stop, andthen release it, during each complete manual operation thereof thereby remaining out of engagement with said spring stop un til returned to its normalposition.
